You can flex, or test, the parameters that you have applied to the family framework. To flex the framework, you adjust the parameter values, making sure that the reference planes to which you applied the parameter change accordingly. Flexing is a way to test the integrity of the parametric relationships. Flexing early and often as you create families ensures the stability of the families.
To flex the framework
The Family Types dialog displays. Although you have not defined any family types yet, the dialog lists the parameters that you created.
The family framework should adjust to reflect the updated parameter values.
The more extensively you test the parameters, the more likely you are to create a stable family.
